Description

A kind of imitative metal refrigerator lining and its forming method
Technical field
The invention belongs to imitate metal refrigerator lining technical field, more particularly to a kind of imitative metal refrigerator lining and its molding Method.
Background technique
In refrigerator industry, there are two ways to making refrigerator lining that there is metal-like or metallic luster, commonly use:
The first: making refrigerator lining using true metal, such as: stainless steel materials.This method improves the matter of refrigerator really Sense and class, but its it is significant the disadvantage is that: process flow is complicated, and mold investment is big, and scrap build is more.Meanwhile when fair line production, Easily occur the mass defects such as knocking, touch, draw, and be difficult to repair, causes product yield relatively low.
Second: metal powder is added in ABS or HIPS pellet and is extruded into plate, plate plastics sucking moulding is then made into ice Case liner.The imitative metal inner lining made of this method, has metallic luster, and compared to the 1st kind scheme be not both excessive to set Standby transformation, will not occur the mass defects such as knocking, touch, draw easily.But the significant drawback of this method is: in ABS or HIPS pellet After metal powder is added, material fluidity is substantially reduced, and the compatibility of ABS or HIPS and metal powder is poor, easily leads to product table There is the unequal obvious mass defect of dark line, glossiness in face.Meanwhile in ABS or HIPS pellet after addition metal powder, material performance Change, it is necessary to newly open plastics suction mould just and can guarantee liner Forming Quality, material can not be compatible with existing mold reduce its The probability promoted and applied in refrigerator lining.
The present invention provides a kind of imitative metal refrigerator lining and its forming method, solves to make refrigerator lining using true metal When, process flow is complicated, and mold investment is big, and scrap build is more, the low problem of yields;Meanwhile it solving to use ABS or HIPS When addition metal powder makes imitative metal inner lining in material, need newly to open plastics suction mould, and product surface dark line, glossiness easily occurs not The problem of equal-quality defect.
Summary of the invention
The purpose of the present invention is to provide a kind of imitative metal refrigerator lining and its forming methods, pass through ABS plate or HIPS plate Metallic film is imitated in surface thermoprint, and is prepared into refrigerator lining using the ABS plate or HIPS plate of the imitative metallic film of thermoprint;Make in refrigerator While lining has metal-like or metallic luster and uniform gloss, reduces mold investment, reduces scrap build, process flow letter List and yields are high.
